IMPROVEMENT IN HEAT-RADIATORS.

Specification forming part of Letters Patent No. 4!,061, dated January5, 1864.

To all whom it may concern.-

Be it known that I, ASA G. EDWARDS, of Southampton, in the county ofHampshire and State of Massachusetts, have invented a new and ImprovedHeat-Radiating Apparatus for Stoves, Furnaces, 8m; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is: a side sectional viewof my invention; Fig. 2, a horizontal section of the same taken in linea; m, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention consists in havingaseries of tubes placed transversely ina pipe connected with or leading from a stove, furnace, or any heatingapparatus, the ends of said tubes communicating with the externalair,and a portion of them being allowed to turn, and provided withflanges to serve as a damper, and using, in connection with the tubesaforesaid,a spiral flange, all beingarranged as hereinafter set forth,whereby the heat within the pipe is radiated from it, and by a verycompact and simple means.

To enable those skilled in' the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a tube or pipe, the ends of which may be of circular form,so as to admit of being applied to an ordinary stove at the lower partof the stove-pipe, or at any part thereof, or to any part of the hotairpipe of afurnace. The central part of A may be of quadrilateral form andsomewhat greater in diameter than at its ends, as shown clearly in Fi 1.

Through the central part of the tube A there passes transversely aseries of tubes, B, the ends of which communicate with the external air.Any desired number of these tubes B may be used, and the upper ones areplaced loosely in the tube A, so that they may turn therein, andprovided with flanges a to serve as dampers, the tubes to which theflanges are attached having handles at one end for the purpose ofturning or adjusting them.

0 represents a spiral flange, which is atside of A, so that its heatwill be radiated from A, and not allowed to pass centrally through it,as would be the case were the spiral flange not employed, as the hottestair is at the center of the current. The flange C also causes the heatedair to be scattered or spread,so that it will strike or comein contactwith all the tubes B, thereby preventing the latter from being burnedouta contingency which would occur were the heated air allowed to passdirectly or unobstructed through A, or if the flame of the tire wereallowed to strike directly against them, in which case some parts of thetubes would be subjected to greater heat than others. Besides, theheated air is made to take a circuitous route and time given it to partwith its caloric. The external air passes directly through the tubes Band absorbs the heat therefrom.

I do not confine myself to any particular point for attaching the tube Ato the pipe of the stove or furnace.

I do not claim, broadly, the employment or use of heat -radiating tubespassing transversely through a drum or tube, for they have beenpreviously used; but,

Having thus described my invention, what I do claim as new, and desireto secure by Letters Patent, is

1. The employment or use in a drum or pipe of aseries of heat-radiatingtubes, B, acertain number of whichare movable or allowed to rotate, andprovided with flanges a to serve as dampers, substantially as herein setforth.

2. The tubes B, movable or fixed, in combination with the spiral flangeC, said parts being arranged within the tube A, to operate substantiallyas set forth.
